Paragraph 0044-0051, (2021/02/10)
The invention discloses an acrylamide monomer for synthesizing a high-molecular-weight polyacrylamide drag reducer and a synthesis method of the acrylamide monomer. The structure of the acrylamide monomer is shown as a formula (I), and R1 and R2 are respectively and independently selected from hydrogen atoms and substituted or unsubstituted C1-C12 alkyl. The preparation method of the acrylamide monomer comprises the following steps of: S1, reacting N-hydroxymethyl acrylamide with alkali and an acetylation reagent to obtain N-acetoxymethyl acrylamide; and S2, reacting the N-acetoxymethyl acrylamide with alkali and amine to obtain the N-(substituted aminomethyl) acrylamide monomer. The hydrophilicity and hydrophobicity of the acrylamide monomer prepared by the method can be adjusted throughcarbon chain structures in R1 and R2, and a polyacrylamide aqueous dispersion prepared from the acrylamide monomer has high apparent viscosity, high molecular weight and high dispersion stability. Themethod is simple in process operation, mild in reaction, easy in product purification and high in yield.

The traditional thermal Mannich reaction is unsuitable for preparing polymerizable N-methylene amino substituted acrylamides and methacrylamides. Herein we provide a facile multi-gram high yield synthesis of these monomeric precursors to stimuli-responsive polymers by the addition of acrylamides and methacrylamides onto in situ generated or freshly isolated methylene Schiff base (iminium) salts. The X-ray crystal structure of the hydrated iminium salt, 1-(hydroxymethyl)azocan-1-ium chloride and monomer·HCl salt (N-[(azocan-1-yl)methyl]prop-2-enamide hydrochloride) is described.

Synthesis of N-(dialkylaminomethyl)(meth)acrylamides from (meth)acrylamide, formaldehyde, and dialkylamines in aqueous solutions was studied. The features of the main and side reactions were examined. Conditions were found for formation of target products with the yield and selectivity close to 100 percent.
